It will mark the first Supercars event at Sandown since 2019, with the iconic Melbourne circuit missing out in 2020 amid pandemic disruptions.
Supercars will assess the opportunity to race in the November 19-21 slot at Albert Park, but an additional event on the current 12-round schedule hasn’t been confirmed.
"This is the right decision and we thank Formula 1 management for their co-operation in setting a new schedule for the 2021 season," Minister for Tourism, Sport and Major Events, Martin Pakula said.
"The Australian Grand Prix is one of the great events in the world and we’ll make sure it can be run safely and successfully in November."
Australian Grand Prix Corporation Chairman, Paul Little added: "We’re very excited to be able to confirm the rescheduling of the Formula 1 Australian Grand Prix to 18-21 November 2021.
"This wouldn’t have been possible without the strong support of the Victorian Government and Formula 1.
"We’d like to thank our loyal motorsport fans and employees for their understanding in these challenging times."
Tickets for the Sandown Supercars event will be on sale shortly.
